Look at the picture.

ΔZYX and ΔDYC are similar. Therefore the lengths of sides are in proportion:

\dfrac{DC}{ZX}=\dfrac{DY}{ZY}

DC = x

ZX = 16

DY = a

ZY = a + a = 2a

Substitute:

\dfrac{x}{16}=\dfrac{a}{2a}

\dfrac{x}{16}=\dfrac{1}{2}       <em>multiply both sides by 16</em>

\boxed{x=8}

<h3>Answer: CD = 8</h3>

Imaginen que un maratonista corre toda una carrera a una velocidad constante. Después de dos horas lleva recorridos 22 km
saw5 [17]

For this case we have:

If after 2 hours the marathon runner has traveled 22 kilometers we have:

2h -----------> 22km

Applying a rule of three, we can know the time it takes to run 42km. So, we have:

2h -----------> 22km

x -------------> 42km

Where "x" is the time it takes to travel 42km. Resolving we have:

x = \frac {(42 * 2)} {22}

x = \frac {84} {22}

x = \frac {42} {11}

x = 3.82 hours

Thus, after 3.82 hours the marathon runner will travel 42km.

Answer:

3.82 hours
